Abstract

A dimming module and a solid state lighting device are shown. The dimming module includes a rectifying circuit, a phase control circuit, a processing circuit and a first driving circuit. The rectifying circuit is configured to convert an input AC voltage to a rectified voltage signal. The phase control circuit is configured to receive the rectified voltage signal and a dimming command, and output a control voltage signal correspondingly in which the phase control circuit controls a phase delay angle of the control voltage signal according to the dimming command. The processing circuit is configured to receive the control voltage signal and adjust a first driving voltage signal according to the phase delay angle. The first driving circuit is configured to receive the first driving voltage signal to drive a first lighting module.
